"Cloud network integration + smart operation" to crack the Internet era Telecom pipeline problems

"We are still in the infancy of the Internet," Kelly, chief editor of Wired magazine, said in a single interview. Over the past 20 years, we have had a lot of important inventions and products, but there are more products are not developed, we are just at the beginning of such a process. Even in such an internet baby stage, it has brought about great changes in our work and life, and the internet is speeding up in all industries. As the basis of the information industry, the telecom operation industry also clearly shows this trend: operators voice, text messaging and other basic business growth slowed year in, the emerging data-focused internet value-added services grow rapidly. However, the rapid growth of data traffic has brought new "happiness troubles" to operators, and a large number of OTT business free or low cost to use carrier network, leading to telecom operators "flow and income scissors" expanding. Whether there is a new way of network construction can support the new business model innovation, help the operator to become the key link in the Internet industry chain again, become the problem that the industry needs to solve now. The internet has triggered new business rules as the industry chain inextricably linked to and from the Internet, telecom operators can learn from the network SP successful Internet experience. Internet service providers value the product experience, using the model of product operation and business income separation. Internet companies divide marketing objects into two groups: Users and customers. First, by offering free, to improve the experience of the way to obtain a large number of users, such as Tencent QQ currently up to 818 million of the monthly active users, followed by a large free user base, to attract advertisers, value-added services providers, app developers, to carry out the charging, to achieve user size and flow of cash; At the same time, through differentiated services to achieve "free users" to "pay customers" transformation, further increase revenue, form a benign business operation model. As shown in Figure 1. 498) this.width=498 ' OnMouseWheel = ' javascript:return big (This) ' Width= "592" height= "290" border= "0" alt= "src=" http ://s7.51cto.com/wyfs01/m02/50/d5/wkioovle__hryoplaacfhxqimya925.jpg "/> Figure 1 Internet profit model operators the current business model is relatively single, users are customers, Due to the inability to provide differentiated service experience, the income form is relatively single, only the most basic cost of pipeline access. Operators need to speed up their Internet capabilities in order to change the way carriers get caught in the trap of being "piped". The ability of Internet service of existing operators can be divided into two types: North and South capability, and the two abilities are fragmented in some degree. North to the Internet SP to provide IDC room rental, income is still based on basic resources business, relying on seat rental, host hosting, bandwidth outRent and other basic business profit level has not been significantly improved; South to provide broadband users with network access capabilities, the number of users x bandwidth monthly fee (ARPU) = Broadband revenue, this simplistic business model makes broadband revenue growth entirely dependent on the user size, once the number of users touch the ceiling, The pull effect of broadband revenue will obviously disappear. If the operator can integrate the north-South capability, will expand the IDC ability to the metropolitan area Network, the metropolitan area network ability at the same time further fusion IDC business, this has hoped realizes "the naked Pipeline" to "the Intelligent pipeline" transformation, through the network structure transformation realizes to the new business model support. As shown in Figure 2. 498) this.width=498 ' OnMouseWheel = ' javascript:return big (This) ' Width= "547" height= "" "border=" 0 "alt=" "src=" http ://s6.51cto.com/wyfs01/m02/51/d2/wkiojllfaamispcdaab_d0jdkty835.jpg "/> Figure 2 Cloud network integration of north-South two-way value-added services and profitability cloud network integration, the network" thin Body " The trilogy's Internet capabilities offer new requirements for operators ' networks: a more high-speed flat, converged business, lower cost, and easier to operate. The next few years will usher in the virtualization, cloud computing, Software definition SDN, network function virtualization NFV technology, such as the focus of the new concept of technology application will profoundly change the existing operator network. Based on the current situation of operator network and the maturity model of technical capability, Hua San Company proposed the Flex Evolution route of Operation Network. As shown in Figure 3. L FlexNet phase through the application of virtualization technology, adjust and optimize the existing network architecture, for cloud network integration to prepare; L The Flexpop phase realizes the convergence of the carrier's north-south capability, and the pop point after the cloud network fusion becomes the new income center; L FLEXNFV Phase introduces SDN/NFV technology, Further reduce costs, improve the flexibility of operating capacity, the ultimate operator will realize the smart operation of the Internet, firmly control the "smart pipeline" core resources. 498) this.width=498 ' OnMouseWheel = ' javascript:return big (This) ' Width= "587" height= "287" border= "0" alt= "src=" http ://s1.51cto.com/wyfs01/m02/50/d5/wkioovlfaa6szmdkaacyvbra3e4564.jpg "/> Figure 3 Carrier Network Flex Evolution three phases to achieve flex smart operation, First, you need to simplify your existing network architecture. After decades of accumulation and construction, operatorshas built a wide coverage, equipment, a large number of large-scale network. In the case of fixed network broadband, a large metropolitan area network has thousands of converging/access rooms, OLT, DSLAM, switches, BRAS, SR network elements in thousand; If you consider wireless broadband network, the number of devices network is larger, Tancheng thousands of base stations, hundreds of thousands of wireless AP access points, plus matching PTN /IP ran bearer network, such a complex network if not first "thin body", to talk about "smart operation" is no less difficult than the requirements of "elephants with fingertips to dance." Virtualization technology has been widely used in the area of LAN, such as data center, can effectively streamline network architecture, improve reliability and simplify operation and maintenance management. With the improvement of technology maturity, the virtualization technology (including N:1, 1:n, vertical virtualization, etc.) is more and more used in metropolitan area network and WAN scene. For example, the metropolitan area Network convergence layer MSE/SR can first deploy horizontal virtualization, to achieve a number of devices virtual logic of a device, while reducing network elements, effectively solve the traditional VRRP and other technologies can not be completed by the two-machine, multi-machine hot standby requirements. After the horizontal integration, the further deployment of vertical virtualization technology, the remote Olt, IP RAN, AP and other Access devices virtual remote extension port, forming an ideal "no Layer access Network" architecture. Through the FlexNet network virtualization phase of deployment, the operator's network will become "light", more flat and simple, with cloud ready ability, for the subsequent cloud network integration lay the foundation. As shown in Figure 4. 498) this.width=498 ' OnMouseWheel = ' javascript:return big (This) ' Width= "522" height= "265" border= "0" alt= "src=" http ://s7.51cto.com/wyfs01/m02/50/d5/wkioovlfabrzmz-saabhdshnibe467.jpg "/> Figure 4 flexnet City Network Virtualization Network, Flexible and diversified business flexnet phase completed the "Light" network adjustment, but still did not solve the operator to face the "scissors" problem, with the continuous increase in traffic, in order to meet the bandwidth requirements of the network construction costs and new income can not match. In the Flexpop phase, new traffic models and network structures are needed to support new business models and generate more revenue. Operators can start with a differentiated application experience, follow the Internet service provider, and change from a simple forward charge to a forward + back charging capability. The key to improving the application experience is to achieve business and network integration. Network can dynamic perception of business, according to different business needs, some business centralized deployment, some services using centralized + distributed push, the operator's network from the original "Exchange Bureau" as the core of the transferinto a "pop point" with business as the core. Each pop point can be understood as a small data center that takes a large cloud data center business to the ground in the area. Through the transformation of the Flexpop stage, the network of operators realizes the initial fusion of cloud network, so that "there is a cloud in the cloud". As shown in Figure 5. By activating the current network of a large number of convergence, access to the computer room resources to enhance the ability of operators to provide the Internet, these resources are the emerging Internet service providers are urgently needed but can not be able to have the ability, both sides have a good foundation for win cooperation. 498) this.width=498 ' OnMouseWheel = ' javascript:return big (This) ' Width= "493" height= "257" border= "0" alt= "src=" http ://s8.51cto.com/wyfs01/m02/50/d5/wkioovlfacjbvxoqaabz0s4ox7g952.jpg "/> Figure 5 Flexpop City Resources Cloud completed the FlexNet modulation framework, Flexpop The evolution stage of income increase, SDN/NFV and other technologies will further help operators to reduce construction and operating costs. The existing network equipment uses the special hardware chip, the development solidified the specialized software which is difficult to expand, causes the operator the purchase cost, the Operation dimension cost, the expansion ability cannot attain the best condition. NFV Network function Virtualization technology based on the standardized x86 server architecture, dynamic loading software, the bras, Cg-nat, FW, LB, DPI, SGSN, GGSN and other dozens of special hardware devices into a standard hardware configuration, to save power, space, reduce capex/ Opex has a huge advantage. SDN software definition capability once combined with NFV, SDN hardware and software decoupling, flexible deployment capability, plus NFV standard low-cost normalized hardware equipment, will produce 1+1>2 effect. Network can be based on the needs of the business dynamic deployment, on-demand cancellation, unified control, at this time the cloud network has been deeply integrated, so that the cloud is the net, the net is the cloud. As shown in Figure 6. 498) this.width=498 ' OnMouseWheel = ' javascript:return big (This) ' Width= "498" height= "267" border= "0" alt= "src=" http ://s3.51cto.com/wyfs01/m02/51/d2/wkiojllfad2jgu7saab2hholiw8736.jpg "/> Figure 6 Architecture Software Network Evolution will not happen overnight, new technology, business, New information business forms give us endless thoughtLike, the Internet in the eyes of Kelly will also take the baby stage, we will live in the cloud in the future, our life, thinking will no longer be the traditional way, but a new perspective.
